QUB³D (sometimes written as QUB3D or QUBED) is a video game in Grand Theft Auto IV which you can play on an arcade machine. The game is made by Rockstar Norh and is probably based on Tetris. The goal is to put cubes of the same colour next to each other. When there are at least 4 cubes of the same colour vertically or horizontally next to each other, they will disappear and you will get some points. If you want to get the highscore number one, you need to get 10 950 points. You can get in the top 10 highscores before you have this great score, but then you will not get the percentages and the Achievement / Trophy "King of QUB3D". The highest score is not so difficult to get, it's just a matter of patience. When the cubes get to the top of the grid, the game will end and the score you have on that moment will be your score.
The cubes will always fall in pares of 2. First there will be only three kinds of colours: green, blue en red. From the moment you get at level 5, yellow cubes will come. At level 10 there will come pink cubes, and at level 15 orange cubes.

Hints and tips

Use specials, these are handy if you do not know what to do.

Save your specials for later if you don't need them.

When you have a pair of cubes, you can let one disappear by let them go down horizontally and when the cube you want to keep can't go down anymore, you do the left analogue stick to the left or to the right, so the cube you don't need any more will get on the other cube and will disappear.
